(Cl. 105-281) 1 \ ' This invention relates to improvements in ‘ 2 n _ construction the‘entire door is located between depending aprons disposed at the ends of the hoppers, and whereas the patented structure dump ‘cars of the'type having discharge hoppers and control doors for the hoppers which selec tively direct the discharge of the lading either constitutes a marked advance over car construc inwardly between the rails of the track or out tions prior thereto and is highly satisfactory in wardly beyond the rails of the track. use, it nevertheless includes as an unavoidable It is an object of this invention to provide a feature the disposition of the end frame beams dump car of the type referred to, which is better , of the main door in the discharge openings so adapted for use both as an ordinary hopper car and as a ballast car for discharging ballast along that when the secondary doors are opened to effect a discharge of lading outside of the rails of the track, these beams to some extent obstruct the free ñow of lading at the ends of the hopper the tracks inwardly and outwardly of the rails. Whereas dump cars of certain constructions openings. > now in use are employed both for carrying vari ous types of lading, such as coal and the like, Accordingly, it is now found desirable to pro in' the manner of ordinary hopper cars and at 15 vide an improved construction which employs a the' same time for carrying ballast for discharge inwardly and outwardly of the rails of the track, modified and diiîerent type of- door which „re-« moves the main door frame members from the space between the depending aprons, or, in other certain structural characteristics of such cars adapting them for such dual use have resulted in words, removes all portions of the door frame a sacriñce of certain advantages which would 20 from the discharge space provided by the hopper openings. Itis also desirable to locate the end otherwise be attainable,` especially in the use of such cars as hopper cars. frame beams outside .of the hopper aprons so The sacrifice of one advantage is due to the that such beams will be removed from contact with the lading and thus be protected from fact that when used as ballast cars, the hoppers must have relatively long discharge openings 25 erosion which would otherwise occur when lading with controlling doors pivoted- on axes extending such as coal and gravel are being handled. ` Accordingly, it is a` further object of this in longitudinally of the car in order that the lading may be selectively directed either inside or out vention to provide an improved car construction side of the rails. Thus when cars so constructed of the general type disclosed and claimed in appli are used as ordinary hopper cars, and the lading caht’s Patent No. 21,152,835 but which diiîers is discharged into receiving bins, the discharge 30 therefrom in that a clearl and unobstructed dis charge space is provided at all _times Ibetween the openings are too long to adjust the flow of the aprons of the hopper openings, and the end frame beams of the main door are located out side of the hopper aprons instead of between the lading to the usual receiving openings in the track provided at freight yards, unloading stations, coal bins and the like. The customary openings in the track now in common use for receiving lading from hopper cars are usually relatively short and are adjusted in length to the trans verse discharge opening type of hopper.

However, in said patented -55 111g,Y ,., ., r , ' 2,409,856 n ` to prevent the lading from spilling outwardly As hereinafter more specifically pointed out, the objects and advantages of this invention are realized by providing an improved door construc tion which has the side or supporting frame members for the main door located beyond or outside of the depending aprons of the hopper, and providing a secondary door which occupies the entire space between the opposed apron members. . 4 3 . Other objects of this invention, not lspecifically enumerated, will readily appear to one skilled' in over the edges of the doors when the doors are open. As illustrated in Figures 2 and 3, these aprons will confine the lading to flow olf of the lower edge of either the main or secondary doors, as the casel may be, in the intended manner to control the discharge of such lading. Below the lower edges 26 of the end slope sheets I9 and the lower edges 2_3 _of the _slope sheets I5, l crack-closing members 42'! are provided, secured to its associated apron 30.'

The main railway car constructed in accordance with this door 25 comprises a body plate 39 to which the invention. link connecting members 40 are secured. The Figure 2 is a fragmentary transverse sectional View in elevation of the car shown in Figure 1, 20 plates 39 are supported and stiffened by the longi tudinally extending Z bar 4I and the channel iron disclosing the doors adjusted for discharging the 42.

'Referring to the drawings, it will be noted that this invention is illustrated as embodied in a car having a center sill I0 and side sills II, which form the main supporting framework for the body of the car. The car body consists of side walls I3, en_d walls I4 and end slope sheets I5 which direct the lading of the car centrally to the hopper openings I6 shown in Figure 4. Over lying the center sill is the usual inverted V shed ding plate I'I and on the outside of the two hop pers I6 are shedding surfaces I8. At the central portion of the car or at the' location between ad jacent hoppers are shedding surfaces I9, which with the sloping surfaces 20 depending from the have their outer edges stiffened and supported by Z bars 5I, Hinge members 52 carried by the angle irons 50 connect to hinge brackets 53 car ried by the channel irons 4‘2 of the main doors; Brackets 54 on the under sides of the door plates 49 serve as connecting means for the'ends of chains 55 which pass up over shafts 55 by rotation of which the secondary doors may be raised and lowered in a conventional manner. ' As clearly shown in Figure 5, the secondary door plate 49 is of such length as to fully close the opening between the hopper aprons _30, and the arms 43 of the main door section extend closely adjacent the outer faces of the aprons 30. The‘door assembly is operated to open the en 0 tire assembly by rotating shaft 46 in the clock wise direction to the position shown in Figure 2.

With either type of discharge therefore the full effective length of corner'points IUD and the hinge axes 24 of the center sill and the above-mentioned shedding sur faces and plates constitute the hoppers of the car.
